Ukulungiswa kwe-Valve VAZ 2114

Namuhla, noma iyiphi imoto yesimanje, ngaphandle kwezikagesi, inenjini yomlilo yangaphakathi enomshini wokusabalalisa igesi. Amapharamitha amaningi ancike ekusebenzeni okulungile kwalolu hlelo. Futhi lezi zihlanganisa ukusetshenziswa kukaphethiloli, ukusheshisa injini, ukusebenza kwemvelo kanye nezinye izinkomba ezibalulekile ngokulinganayo. Ukusebenza okuvamile kwendlela yokusabalalisa igesi kuqinisekiswa ukulungiswa okulungile kwezikhala phakathi kwe-valve kanye ne-pusher yayo.

Uma igebe likhulu kakhulu, i-camshaft cam izoshaya i-thrust plate, futhi konke lokhu kuzoholela ekulimaleni okukhulu kwezingxenye zenjini nezindlela. Futhi, i-valve ngeke ivule ngokugcwele uma kudingeka, ngaleyo ndlela ivimbele ukunyakaza kwe-exhaust noma ingxube ye-air-fuel, kodwa kuye ngokuthi uhlobo lwe-valve. I-Inlet - inesibopho sokuhlinzekwa kukaphethiloli, i-exhaust - yamagesi aphumayo athunyelwa ku-multifold exhaust.

Umgomo wokusebenza kwe-valve mechanism

Ngokuphambene nalokho, uma i-valve iboshwe ngokuqinile, ukulimala kwemishini ezingxenyeni zenjini kuzoba ngaphansi uma igebe likhulu kakhulu. Kodwa umsebenzi injini ngokwayo kuyoba kubi kakhulu. Kungenxa yokusebenza kahle kwenjini ukuthi kuyadingeka ukulungisa ngokucophelela ama-valve ezimotweni ze-VAZ. Le nqubo yenziwa ngezindlela eziningana. Okokuqala ukuthi i-pusher ihamba ngaphansi kwethonya le-nati esiqwini. Okwesibili ukukhethwa kwama-spacers of the ukushuba oyifunayo. Eyesithathu i-automatic, ilawulwa umfutho kawoyela wenjini kuma-hydraulic lifters.

Setha igebe ku-VAZ 2114

Esimweni sethu, emotweni ye-VAZ 2114, le nqubo yenziwa ngendlela yesibili, isebenzisa ama-gaskets kanye nethuluzi elikhethekile.

Okokuqala, kufanele uqonde ukuthi ukulungiswa okulungile ku-VAZ 2114 kungenziwa kuphela ekushiseni okungama-degrees Celsius angu-20, lapho insimbi iphumule futhi ingekho ngaphansi kokukhuliswa okushisayo njengenjini eshisayo.

Okwesibili, emotweni ngayinye ethile kukhona itafula lamasayizi wokugunyazwa ngamakhamera we-camshaft aphakanyisiwe.

Kumodeli yeshumi nane, izilinganiso ezilandelayo zisetshenziswa:

• Kuma-valve okungena: 0,2 mm ngephutha lokufunda lika-0,05 mm;
• Kuma-valve okukhipha umoya: 0,35 mm ngephutha lokufunda elingu-0,05 mm.

Ngaphambi kokulungisa, pholisa indawo yenjini, ungasebenzisa isiphephetha-moya esivamile. Ngemuva kwalokho, sisusa ikhava ye-valve, amapayipi, izinsimbi zokuvala, i-casing evikelayo yebhande lesikhathi. Ngemva kokukhulula inadi elibambe ikhebula le-accelerator pedal, linqamule ngokucophelela. Susa umhlangano wezindlu wokuhlunga umoya ukuze usebenze kalula. Ngaphambi kokudiliza, qiniseka ukuthi ubeka ama-wedge ngaphansi kwamasondo futhi uvule igiya elingathathi hlangothi. Ibhuleki lokupaka nalo kumele licushwe.

Ithuluzi elibalulekile

Amathuluzi adingekayo emsebenzini:

1. 1. Izikhonkwane zesokhethi neziphetho ezivulekile;
2. 2. Idivaysi yokwehlisa amapuleti e-valve - ibiza kancane ngaphezu kwama-ruble ayikhulu;
3. 3. Iqoqo lama-probes akhethekile okulinganisa izikhala kumshini;
4. 4. I-Micrometer yokunquma ubukhulu be-gasket;
5. 5. Ukulungisa amawasha: Ukuqina kusuka ku-3 kuye ku-4,5 mm. Ahlinzekwa emakethe ngama-increments angu-0,05 mm. Okusho ukuthi, ungathola amawasha anosayizi we-3,05mm, 3,1mm, njalonjalo aze afike ku-4,5mm. (I-disc ibiza cishe ama-ruble angamashumi amabili).

Inqubo yokulungiswa

Hlola ukuthi amamaki kuma-timing gears kanye nesembozo sekhanda lesilinda somdlalo we-VAZ 2115. Amamaki afanayo kufanele ahambisane ne-crankshaft pulley kanye nesembozo sepompo yamafutha. Okulandelayo, qaqa ama-spark plug ukuze unciphise ukucindezela kusilinda block.

Ngaphansi kwesembozo se-valve ngesikhathi sokuhlanganisa kabusha, faka i-gasket entsha ephathwa nge-sealant emiseleni.

Ukuhleleka kwama-valve Vaz 2114

Lapho ulungisa, qaphela ukuthi iyiphi i-valve ephumayo nokuthi iyiphi i-outlet, umyalo umi kanje:

5 - ukukhululwa kanye no-2 - okokufaka; 8 - okukhipha kanye 6 - okokufaka; U-4 uwumphumela futhi u-7 uwukufaka.

Ukuhamba kusuka ku-camshaft pulley, silinganisa izikhala phakathi kwe-pusher ne-camshaft. Ezindaweni lapho igebe livamile khona, yonke into ihlala ingashintshile. Endaweni lapho i-probe yesayizi efanelekile ifakwa kalula ku-groove, sicindezela ipuleti ngedivayisi yokwehlisa i-pusher, bese sifaka ifulegi ukuze silungise i-pusher. Khona-ke, sisebenzisa ama-tweezers akhethekile, sikhipha i-washer yokulungisa futhi sibheke uphawu lwaso. Uma kunesidingo, linganisa ubukhulu nge-micrometer. Okulandelayo, sikhetha i-washer ekhudlwana, sibeke endaweni futhi siqale sihlole igebe nge-probe oyifunayo.

Ukucaciswa kwama-valve

Uma ingalingani, khona-ke sithatha ithubhu elincane, njalonjalo kuze kube yilapho ithubhu ingena. Kusukela kumehluko phakathi kosayizi wegama kanye nosayizi we-probe, olingana kalula, sibala ubukhulu obufunayo bebha. Siphinda inqubo kuze kube yilapho i-probe iqala ukufakwa nge-pinch encane.

Uma i-probe ingekho elingana, i-valve yelulekile kakhulu! Ngokokusebenza kwangaphambilini, susa iwasha yokulungisa bese ushintshela kwencane.
